René Lohse, married Sachtler-Lohse (born 23 September 1973) is a German former competitive ice dancer.

With partner Kati Winkler, he is the 2004 World bronze medalist and a six-time German national champion.

At the age of 12, he left skating for other sports but two years later Kati Winkler asked him to take up ice dancing with her.

[3] In 1999-2000, Winkler and Lohse's free dance was entitled "Time Goes Millennium", which included techno-style music with ticking sounds, clock images created by their arms and legs repeatedly mimicking clock hands, a rhythmically swinging lift in which Winkler represented a pendulum, and both skaters listening to and looking at wristwatches while walking briskly on the ice.

[5] In 2000-01, Winkler and Lohse became the first German ice dance team to qualify for the Grand Prix Final, where they finished fifth.

They missed most of the 2001-02 season after Lohse fell in practice at the 2001 Sparkassen Cup, injuring the meniscus and ligaments in his knee.
